Une-of thecircuit wires is indicated at 200 and theother :at 201. The bottom-ofthe housing 193 isprovided with a slot 202. Another of the walls of thehousing .193 at its-lower end is provided with a slot 203. Arrangedwithin thehousing 193 is a plate 204 of insulation.v 'Secured "to theplate-204 'is a pair of strips of insulation 205 and against the upperportion thereof is secured a plate 206 of insulation. Secured tothelower end of the strips 205 are small blocks 207, 208 of insulation.Slidably adjustable between the strips 205 is a vertically movablecarrier 209 of insulation and which has embedded in one face thereof atapered contact member 210, of the same length as the length of thecarrier 209 and which gradually increases in width from the bottom edgeto the top'edge of the carrier 209. The retaining blocks 207. 208overlap the carrier 209. The carrier 209 is vertically adjusted andmaintained in its adjusted position and the means therefor is asdisclosed in my application aforesaid and it is thought unnecessaryto-specifically describe and show the same. The circuit wire 201 iselectrically connected to the contact 210. The cir cuit wire 200 iselectrically connected to a conducting arm 64, which is secured at oneend to the upper portion of the plate 206 and hasits other end bentinwardly or inturned upon itself as at 65 for the purpose of forming acontact abutment. Secured to the plate 206, below the arm 64: is a pairof spaced-stop pins 66', 67. Pivotaily connected' to the plate 206, asat 68'. and below the pins 66', 67' is an oscillatory conductor memberwhich normally contacts with the abutment formed by the inturned end ofthe arm 64 and said conductor meniber-is formed of an invertedyoke-shaped lowerfportion 69' having an upwardly extending arm 70-formed integral therewith. The arm 70' extends between the pins-66 and07' and below the inner face of'the arm 04' The lower portion 09 of theconductor member depends below the plate 206 andthe arms of said memberare indicated at 69 and 70-. The said arms are arranged in the path ofthe circuit opening and closing element of a spring controlledoscillatory circuit opening and closing mechanism which is arrangedbelow the plate 206 and is engaged by a spring controlled latchingmember 211 which extends through the slot 203 and is positioned in thepath of the actuating member 197. The said oscillatory circuit openingand closing mechanism not only coacts with the said conductor member.but also with the contact 210. I 1

Theoscillatory circuit opening and closing mechanism is shifted to closethe circuit through the medium of a controlling spring therefor andreturned to inactive position. or positioned to open the circuit, alsoby a controlling spring. The controlling springs will'be presentlyreferred to. The oscillatory circuit opening and closing" mechanism alsoincludes a governor to provide for its operation at uniform speeds whenreleased to close the circuit and shifted'to inactive position to openthe circuit.

The spring controlled oscillatory circuit opening and closing memberincludes a headed pivot 71 upon which is pivoted a bell crank memberhaving its arms indicated at 72", and 72" and connected to the arm 72 isa toothed quadrant 73. Extending fromthearm 70 to the arm 72 is acircuit con ductor 74 whereby said arms are electrically connectedtogether. The arm 72 carries an arcuate bar 75 formed with a seat 76engaged by the latch 211; the latter being: spring controlled, as at211. The controlling sprinfr' for the bell crank lever is indicated at77. The quadrant T3 is employed for actuating the governor 79 positionedin the path of the double-armed lever 80. One of the arms'of the lever80 is indicated at 1 and which coacts wi h the lug 79 The other arm ofthe lever 80 indicated at 82 and which coacts with a return spring 83fixed to apart of the machine body.

Secured t0 the arm 72 of the bell crank and of less length than thelength of-said arm is a bar 85'.

- The elements of the circuit opening and closing ole-vice are brieflyreferred to but for a more detailed and specific description of theelements of the-device reference is had to the applicantsco-pendingapplication aforesaid.

The bar 85-- aots as a m'eans'to oscillate the conductor-member so thatthe arm 70' there of wilt-he :inoved into androut of engagement with the-int urned portion of the arm 64: and as before'stated the inturnedportion 65 constitutes an abutment contact. Normally the arm Z0 of theconductor member is in engagement with the abutment contact and which iscaused by the bar 85 engaging in the arm 69" of the conductor member sothat the latter will be rocked or shifted to the position shown inFigure 26. When the bar 85 moves in a clockwise direction,=that' is tosay away from the arm 69", the armn72" of the bell crank which is termeda wiper member will engage uvith the=conltact21O and the circuit will bemaintained closedas long as the wiper member is in engagement with thecontact member 210. As the wiper member, arms 7 2, moves with the "bar85 -in a clockwise di rection said bar 85 will engage the arm '60 of theconductor member and shift the arm of the conductor member out' ofcontact with the inturned end 65' of the member :64. When the bar 85"engages the arm 70" the conductor member will be shifted to a positionopposite to that shown in Figure '26 and the arm 70 thereof will engagethe p n 66. At this time the bar 85' will be moved in a counterclockwisedirection and towards the arm 69" and during such movement of the bar 85the wiper member, arm 72, will engage the contact 210, but as the arm 70is out of engagement with the inturned portion 65 of the arm 64' thecircuit will not be closed. As the bar 85' moves towards the arm 69" itwill abut the latter and at the time of the abutment the latch 211 willengage the seat 76' and maintain the parts in the position shown inFigure 2. The shifting of the bell crank formed by the arms 72' and 72is caused by the spring 77, when the latch member 211 is shifted fromen'- gagement with its seat 76, and the actuation of said bell crank ishad against the action of the spring 83' which is placed under tensionthroughthe medium of the lever '80. The spring 77 provides for movingthe arm 72 ina direction towards and over the contact 210, and thespring 83 acts as a means sary for the application of light rays to aparticular photographic plate.

The combined stop and escapement mechanism for the sprin controlledcarrier per.- mits of the latter shifting transversely the desiredextent when successively printing the design or matched portions thereofin a row on the transfer plate '82 and such mechanism is actuated torelease the carrier when the shift ng mechanism for the lamp house ismoved upwardly through the medium of the controlling springs therefor.

The combined stop and .escapement mechanism for the gravity movabletransfer plate holder permits whensuch mechanismis-manually actuated theshifting of such plate holder downwardly the desired .distance toposition another portion of the transfer plate82 so that such portioncan be printed with another row ofdesignsor matched portions of thedesigns and with-the lower row matching with theup'per row. i

The limit members of reach escapement mechanism can be adjusted on theirrespectivezshaft so that the desired shift of the carrier or transfer lplate holder can be obtained for the purpose of matching the prints. The'bevell-ing of the stop lugs and stop members of the .esca pementmechanisms will permit of the carrier or the transfer plate 'holder tobe shifted .to initial position.

The carrier is shifted to initial position on'the actuation of the rockshaft 104 by the handle member 106. iChe transfer plate holder isshifted to initial position manually or any suitable means can beemployed for such purpose.

The construction of the elements 104, 106, 107, 109 and 111, which formthe means for shifting the carrier to initial position, is such as notto interfere with the shifting of the carrier from initial position.

It is thought that the operation of the -machine is clearly understooc lin view of the specific operation as set forth in con ection with theseveral mechanisms thereof, but it will be stated that on the depressionof the lever '1' 1 the lamp house carrying the printing plate 32 will beshifted until said plate enga es the transfer plate 82 and at which timethe lighting circuit will be closed, under such conditions printing thedesigner a permit of the -latte1 matched portion thereof on the plate82.
